20% faster `try`

Following up on #33747, this takes things a step further by pulling out
the method name from the arguments array, letting us skip an allocation
in the case where there are no arguments -- notably, this also no longer
*requires* the splat to be an array, allowing us to benefit from
optimizations in Jruby (and maybe MRI in the future) of skipping the
array allocation entirely.
